Cancer incidence in Blantyre, Malawi 1994–1998

Abstract

SummaryIn this paper, we report the ®rst results from the population-based cancer registry for Blantyre district, Malawi, for the period 1994±1998. In this 5-year period, 1245 cases were recorded in males (an estimated age-standardized incidence of 92.0 per 100,000) and 1003 in females (an age standardised rate (ASR) 1 of 88.8 per 10 5 ). The overall percentage of cases with histological veri®cation was just 41.8%, indicating that case-®nding outside the laboratory had been quite successful; nevertheless the rather low rates suggest possible underdiagnosis of cancer, as well as cases missed. As in other reports from the region, the contemporary pattern is dominated by Kaposi's sarcoma (KS) (55.2% cancers in men, 28% in women), the effect of the evolving epidemic of AIDS. The incidence of cervix cancer in women is high (ASR 26.2 per 10 5 ), and there are moderately high rates of oesophageal cancer (ASR 15.4 per 10 5 in men, 9.3 per 10 5 in women). In childhood, the cancer pro®le is dominated by Burkitt's lymphoma, which accounts for 42.4% of cancers; KS is now the second most frequent cancer of childhood.

Spectrum of Pediatric Cancers in Mozambique: An Analysis of Hospital and Population-Based Data

“…This is similar to what was reported in Zambia [23], using data from histopathological records of the University Teaching Hospital, which was the national referral center, where 32.5% and 19% of all cases diagnosed in 1990–1992 were lymphomas and Kaposi sarcomas, respectively. Similarly, lymphomas accounted for more than half of the diagnosis in Blantyre, Malawi, during 1991 and 1998 [24]. Data from the Harare Cancer Registry for 1993–1995, in Zimbabwe, showed that leukaemia, Wilms tumor, and retinoblastoma accounted for 15.1%, 14.4%, and 11.0% of the diagnoses, respectively, and that Kaposi sarcoma and lymphomas accounted for 10.3% and 8.2% of the diagnoses, respectively [25].…”

Estimating the incidence of colorectal cancer in Sub–Saharan Africa: A systematic analysis

“…The 50 articles considered irrelevant did not comply with the exclusion/inclusion criteria set for this review; however, some were retained for extra information, mainly in the discussion. The 15 relevant articles [10,20,[32][33][34][35][36][37][38][39][40][41][42] were then supplemented by the 21 data sets secured with permission from the IARC [43,44] and the further 21 data sets which were received from the directors of the cancer registries through the IACR [16]. Six articles, which were not suitable for contribution to the estimates of incidence but were sourced for full-text copies, were retained for information on the biological characteristics of CRC diagnosed in SSA.…”
